Anyone know what controller will work w/ the original Dayton 1/2hp DC motor for a Dadant 33 frame extractor?

I don't know if you are looking for an original replacement or a generic.
I have ordered several things from;
SURPLUS CENTER
1-800-488-3407
surpluscenter.com
They also have a catalog.

It is a dc

I bought it from Dadant. They said that it was the same motor that has always been used for the 33 frame extractor.

I have used Dart controls. Cheap and do the job. I don’t know what Dadant does but I would use a drive in current limit mode. It will automatically speed up as the honey is expelled.

More serious drives can do more things. I like Reliance but I see they are bought out by Baldor and I am not sure what products they will phase out. What is the name brand on the drive that you have? Have you looked into fixing it?

Radar, that is way out of my budget range. thx anyway.

Ace, all I know is that it is a Dayton dc 1/2 hp. it is @ my shop 10 miles from here. I need advice on which controller will work @ on low budget.

I suggest that you try to find a nameplate on the motor itself (not the extractor), and pass along everything that is on the nameplate.


If you don't want to buy Dadant's solution, the more information you can provide, the easier it will be to suggest an alternative.

Why is that you think you need a replacement speed controller? What problem are you having? Could the issue be with the motor instead?

Ace, I hate to tell you, but the Dadant control MAY be more than you can imagine. Ours is simple, rugged, yet performs better than a straight up DC drive could. It is a Variac, advanced by a timer motor, that trips a off delay relay, rectified by a bridge.
It is easy to fix, and most parts are generic.

What does the OP have now?

I believe that although the OP does not have money for a Dadant control, that anything less would be a waste of money on a product that would be unsatisfactory, and cause more grief than good. Wait and save your money.

The motor that came with it was not factory original, but a VERY small & modified unit. the controller on it will not work w/my new Dayton (from Dadant).

Roland, when you say "ours" do you mean you work for Dadant or "ours" meaning the one you have?

Lakebilly, You need to talk to "Kent" at Dadant's Metal Warehouse where they make the extractors. I just went thru a problem with ours and he sold us the parts needed for the control. NOT the whole control. We just bought the circuit board and wired the control up ourselves. Works like a charm. Was cheap compared to the control. Nobody else there knew what was going on except him. The Metal warehouse phone number is 217-852-3324, Good Luck.

Thank you!! will do Monday first thing. I had planned on calling Dadant. It's good to get the right guy& # early.

Which extractor do you have? & what can you tell me about wiring it?

Sounds a bit barbaric but it probably works ok. An extractor has a high start up load so any dc drive you pick out should have a very long accel or better yet be able to run in "current limit" otherwise the motor armature will cook. The variac is an analog device which I have no problem with but it requires more "clap trap" to step it up (the accel). This will also cook the armature if done too quickly.

Lakebilly: I do not work for Dadant. The control belongs to Linden Apiary(my son and I)

Ace- I find your comments revealing a lack of real world experience. These motors are generally oversized, so exactly how are they going to overheat from a starting load? If anything, a slow ramp from zero would be worse, because the motor is a TEFC, not a TEBC. It is best, and in the Dadant instructions, to NOT start the motor at less than 30 percent full speed. That is why a standard inverter with fixed Accel rate is bad. Game over, please try again.

Roland go back to school. An inverter is an AC drive, we are speaking DC. They tell you to start at 30% because you are using a variac. At low speed you only have a few coils of the variable transformer taking all the current. A variac is a bad application for a high inertial load. Stick to beekeeping please.

While the speed control offered by Dadant is expensive, one of its nice features is that the extractor speed can be set to ramp up over the entire (possibly 20 minutes or so) extractor cycle. That means you could have it start at say 100 RPM and slowly increase to 350 RPM over the 20 minute cycle, then shut itself off, automatically.

I haven't seen that feature offered in any of the alternatives linked.
